Answers
At 7:00am,he started traveling at the speed of 36 kmph
His car went out of his order and he stop
Resting 35min
He returned at the foot speed of 14kmph
Reaches at home 1pm.
Time between 7am to 1pm =6hours
Let the distance travelled by a car and foot be x.
Speed =distance/time
Therefore, time = distance /speed
Distance travelled by car = x/36
Distance travelled by her = x/14
Resting time = 35min
1hour =60min
Therefore,6hours = 360min
According to the given condition,
x/36 + x/14 + 35 = 360min
x/36 + x/14 = 360 - 35
By cross multiplying
14x + 36x / 504 = 325
50x = 325 × 504
50x = 163800
x = 163800/50
x = 3276
Therefore,
Distance between car broke
= 3276m= 3.276km
