jet flies over the Air Force Base at 10:20

am At 10:32 am, the plane passes over the

Ilary Base Station, 120 miles away. How fast

is the aircraft traveling?

The speed of aircraft is 600 mph.

Step-by-step explanation:

Given distance = 120 miles

Time for which jet flew : from 10:20 AM to 10:32 AM

Total duration for which jet flew = 10:32 - 10:20 = 12 minutes

(from 10 hours 32 minutes and 10 hours 20 minutes

10 hours gets cancelled, 32 minutes - 20 minutes is 12 minutes)

here time is in minutes, we have to convert it in hours

we know

60 minutes = 1 hour

1 minutes = 1/60 hour

multiplying LHS and RHS by 12

1*12 minutes = (1/60) * 12hour

12 minutes = (1/60) * 12hour

12 minutes = 1/5 hours

We know

speed = distance / time

distance = 120 miles

time = 1/5 hours

speed = 120 miles / (1/5 hours)

speed = 120 * 5 mph = 600 mph

The speed of aircraft is 600 mph.
