Question

A car travels 52 mph for 6 minutes, 46 mph for 3 minutes, 40 mph for the remaining time during a 30 minute journey. find the total distance travelled​​

Answer 1

Answer:

21.5 miles

Explanation:

Distance = Speed * time

Distance  traveled in first 6 minutes = 52 * $\frac{6}{60}$  = 5.2 miles

Distance  traveled in next 3  minutes = 46 *$\frac{3}{60}$ = 2.3 miles

Remaining minutes = 30 - 6 -3 = 21 minutes

Distance  traveled in 21 minutes = 40 * $\frac{21}{60}$ = 14 miles

Total distance traveled = 5.2 + 2.3 + 14 = 21.5 miles
