Answer 1

Explicación paso a paso:

Information:

from 3:00 to 4:30 = 1:30 = 1,5 hours

from mile 50 to mile 155 = 105 miles

1)

If

speed = distance/time

So,

speed = (155 - 50) miles / (4:30 - 3:00) hour

speed = 105 miles / 1,5 hours

2)

If:

speed = distance/time

→ time = distance/speed

So,

1,5 hours = 105 miles / speed

3)

If:

speed = distance/time

→ distance = speed × time

or distance = time × speed

So,

105 miles = 1,5 hours × speed
