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

21.5 miles

Step-by-step explanation:

Distance = Speed * time

Distance traveled in first 6 minutes = 52 *
`(6)/(60)` = 5.2 miles

Distance traveled in next 3 minutes = 46 *
`(3)/(60)` = 2.3 miles

Remaining minutes = 30 - 6 -3 = 21 minutes

Distance traveled in 21 minutes = 40 *
`(21)/(60)` = 14 miles

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