A. 4.5km
B. 6 km

So, t1 - t2 = 15 - ( - 15) = 30 minutes = 0.5 h
Now, let the distance travelled be = x km
So, (x / 3) - (x / 4) = 0.5
⇨ x = 6 km.

Answer: Option C

Explanation:

"Rahim spent exactly 38 Tk on both type of fruits. If he bought only one watermelon and used the rest (38 - 5)  =  33 on pineapple, it would not be 'exact' as 33 can not be divided by 7 (the price of one pineapple)
2 watermelon, 4 pineapple  =  2  ×  5  +  4  ×  7  =  38 Tk
3 watermelon, 3 pineapple  =  3  ×  5  +  3  ×  7  =  36 Tk
So, only by buying 4 pineapples and 2 watermelon Rahim can spend exactly Tk 38."
