12. A car started from Town P and ltravelled towards Town Q at 70 km/h. At the same time a van startedfrom Town Q and travelled to Town Pat 60 km/h. After 11/4
hours, they were 65 km apart, still travellingtowards each other.
(i) What is the distance between the two towns?
(ii) After how many hours of travel would they cross each other?
Answers
Answer:
Distance covered by Car in 11/4 hours.
Distance = Speed × Time = 70 × 11/4 = 192.5 km
Distance covered by Van in 11/4 hours.
Distance = Speed × Time = 60 × 11/4 = 165 km
1.
The Distance between P and Q = 192.5 + 165 + 65 = 422.5 km
Step-by-step explanation:
Answer:
1) • In the given question information given about two cars start from town P and town Q in opposite direction at the speed of 70 km/h and 60 km/h. After 11/4 hours the distance between those two cars is 65 km apart.
• We have to find the distance between two towns.
given:
speed of car =70 kmph
speed of van = 60 kmph
to find :
distance between town p and q = ?
for car :
distance = speed x time
d = 70 x 11/4
d = 385/2
d = 192.5 km
for van :
distance = speed x time
d = 60 x 11/4
d = 15 x 11
d = 165 km
total distance between town p and q :
distance covered by car + van + 65 km
total distance = 422.5km
2) 3 hours 15 minutes
