Captain tellez plans to reach a cruising altitude in his passenger plane and then maintain a cruising speed of 570 miles per hour for approximately 400 miles. which is closest to the length of time, in minutes, that his plane will maintain cruising speed?

a. 0.70
b. 1.43
c. 42
d. 86

option (c)

42 minutes

Step-by-step explanation:

Given in the question:

cruising speed of passenger plane = 570 miles/hour

distance passenger plane travelled = 400 miles

distance = speed x time

time = distance / speed

time = 400 / 570

       = 0.7018 hours

1 hour = 60 minutes

228000 hours = 60 x 0.7018 minutes

                         = 42.1052 minutes

                         ≈ 42 minutes

Closest to the length of time, in minutes, that Captain Tellez's plane will maintain cruising speed is 42 minutes.
