Question

While traveling, John let destination A at 9 am. Driving until 7 pm, he travelled a total of 500 miles. The next day, John left at 9 am and drove until 5 pm, covering 270 miles. What was the average speed for both days, while driving

Answer 1

18 hours 770

770/18 average speed.

Answer 2

The average speed for both days, while driving is 42.77 miles/hr.

Step-by-step explanation:

Given that,

Distance first day = 500 miles

Distance second day = 270 miles

According to question,

The distance covered by the john in 10 hours = 500 miles

Next day ,

The distance covered by the john in 8 hours = 270 miles

We need to calculate the average speed for both days

Using formula of the average speed

`v_(avg)=(D)/(T)`

Where, D = total distance

T = total time

Put the value into the formula

`v_(avg)=(500+270)/(10+8)`

`v_(avg)=(770)/(18)`

`v_(avg)=42.77\ miles/hr`

Hence, The average speed for both days, while driving is 42.77 miles/hr.
