Question : Two cars started from the same piont. First car went towards the north and covered 255 km in 3 hours the second car went towards the south and covered 327km in 3 hours. Find the distance between two cars after one hour.
Solution : Let first car be A and second car be B.
- Distance covered by car A = 255 km
- Distance covered by car B = 327 km
Now,
⟹ speed of car A = covered distance/time taken
⟹ speed of car A = 255/3
⟹ speed of car A = 85 km/hour
Hence, here we know that distance covered by car A after one hour is 85 km.
⟹ Total distance covered by car A = covered distance + covered distance after one hour
⟹ Total distance covered by car A = 255 + 85
⟹ Total distance covered by car A = 340 km
similarly,
⟹ speed of car B = covered distance/time taken
⟹ speed of car B = 327/3
⟹ speed of car B = 109 km/hour
Hence, here we know that distance covered by car B after one hour is 109 km.
⟹ Total distance covered by car B = covered distance + covered distance after one hour
⟹ Total distance covered by car B = 327 + 109
⟹ Total distance covered by car B = 436 km
Now,
⟹ Distance between two car after one hour = Total distance covered by car A + Total distance covered by car B
⟹ Distance between two car after one hour = 340 + 436
⟹ Distance between two car after one hour = 776 km
Answer : Distance between car A and car B is 776 km.
