Answer:
144 minutes
Step-by-step explanation:
Let the time taken be A
Since you can ride 5 miles in 40 mins
Therefore,
5 miles = 40 mins
18 miles = A mins
Cross multiply
A x 5 = 18 x 40
5A = 720
Divide both sides by 5
5A/5 = 720/5
A = 144 mins
At that rate, it’ll take 144 minutes to travel 18 miles
