Question

Suppose you are choosing between two roads. The first route is 70 miles at 55mph, and the second road is 85 miles at 65 mph. Which route would get you there faster, and in what amount of time?

Answer 1

Answer:

Since we Know

Time=DISTANCE/SPEED

Step-by-step explanation:

IN CASE -1 : GIVEN,

DISTANCE=70MILES

SPEED=55 MPH

THEREFORE,

T=D/S

T=70/55

T=1.2 Hr

CASE- 2: Given,

Speed. =65 Mph

DISTANCE =85 Miles

THEREFORE,

T=D/S

T=85/65

T=1.3 Hr

So you should take Road -1

Here the unit of time is in Hr because distance and speed is in miles
