Question

Mike and Jamal are 9 miles apart, and are planning to meet up. Mike is walking at an average speed of 3 miles per hour to meet Jamal. Jamal is driving at an average speed of 25 miles per hour to meet Mike.


Which equation can be used to find t, the time it takes for Mike and Jamal to meet?

Answer 1

Hello!!!!

Mike is walking at 3 miles per hour, so in t hours he walks 3t miles.Jamal is driving at 25 miles per hour, so in t hours he drives 25t miles.They are 9 miles apart, so the sum of the distances they need to travel is 9 miles.
so 3t + 25t = 9
Hope this helps!

Answer 2

Equation used to find t, the time it takes for Mike and Jamal to meet after covering some distance is equals to 25t + 3t = 9.

What is distance?

" Distance is defined as the total space between two end points."

Formula used

Distance = Speed × Time

According to the question,

Total distance between Jamal and Mike 'd' = 9miles

Average speed of Mike = 3miles per hour

Average speed of Jamal = 25miles per hour

't' represents the time taken by Mike and Jamal to meet

Substitute the value in the formula we get,

Distance travelled by Mike 'd₁' = 3 × t

                                             = 3t

Distance travelled by Jamal 'd₂' = 25 × t

                                             = 25t

Equation represents total distance ,

   d₁ + d₂ = d

⇒ 3t + 25t = 9

Hence, equation used to find t, the time it takes for Mike and Jamal to meet after covering some distance is equals to 25t + 3t = 9.
