Question

A motorist travelled from town a to b at an average speed of 54 km/hr. on his return journey , his average speed was 60 km/hr . if the total time taken is 9/1/2 hours when it is in mixed fraction. find the distance between the two towns

Answer 1

Total speed=54+60=114

Total time in improper fraction=9×2+1=18+1=19


By using the Distance formula as we have to find the total distance with the help of total s
red and total time=Speed/Time=Distance

=114/19

Answer 2

Answer: x= 63

Step-by-step explanation:

Let the speed of one motorcycle1 be x.

Then motorcycle2 will be x+7 ((7 kmph faster))

AFTER TWO HOURS

Motorcycle1: 2×x

Motorcycle2: 2×x+7

2x + 2(x+7)+ 34 =300

2x + 2x+14 + 34=300

4x + 48 =300

4x= 300- 48

4x= 252

x= 252÷4

x= 63

Therefore motorcycle1 is at a speed of 63kmph while motorcycle2 is at a speed of 63+7=70 kmph.
