Question

A truck driver travels 93 miles in one hour and 30 minutes at this rate how far will he travel in four hours

Answer 1

Answer: 248 miles

======================================================

Work Shown:

1 hr, 30 min = 1 hr + 30/60 hr

1 hr, 30 min = 1 hr + 0.5 hr

1 hr, 30 min = 1.5 hr

The driver travels 93 miles in 1.5 hours, so his speed is

rate = distance/time

r = d/t

r = 93/1.5

r = 62 mph

In four hours, he travels

d = r*t

d = 62*4

d = 248 miles

---------------

An alternative method is shown below

(93 miles)/(1.5 hrs) = (x miles)/(4 hours)

93/1.5 = x/4

93*4 = 1.5*x ..... cross multiply

372 = 1.5x

1.5x = 372

x = 372/1.5

x = 248

Answer 2

12 because 93+30 =12
