Question

A trip took you 5 hours and you traveled 283.5 miles. If you averaged 49 mph
for the first part of the trip and 60 mph for the 2nd part, how long did you drive
at each rate?

Answer 1

Answer:

1.5 hr and 3.5 hr

Step-by-step explanation:

Time in the first part= x

Time in the second part= 5 - x

• 49x+60(5-x)=283.5
• 49x+300-60x=283.5
• 11x=300-283.5
• 11x= 16.5
• x= 16.5/11
• x= 1.5 hr
• and
• 5-x= 5-1.5= 3.5 hr
