Answer 4

Be careful with the units.
90 minutes is an hour-and-a-half.
If you go 66 mph for an hour-and-a-half, you will definitely not travel 5940 miles.

Answer 6

@Jeff666
Your formula is correct, but since mph means miles per HOUR, you need the time in hours, too.
What is 90 minutes in hours?

Answer 7

one hour and half

Answer 8

Good.
Now use the formula with 1.5 hour

Answer 9

ohh ok then it would be 99

Answer 10

so you would do 90 x 66?

Answer 11

distance = speed * time
speed = 66 mph
time = 1.5 hours

distance = 66 mph * 1.5 hours

What is 66 * 1.5 ?

Answer 12

You convert 90 minutes to 1.5 hours and multiply 1.5 by 66.

Answer 13

ok, it is 99

Answer 14

Correct.
99 miles
