Haji rows his canoe 10 mph in still water. he noticed one day that he could row 4 miles upstream in the same amount of time he could row 6 miles downstream. what was the approximate speed of the current that day? 2.0 mph 3.3 mph 5.0 mph 10.0 mph

Answer : 2.0 mph

Haji rows his canoe 10 mph in still water

Speed of still water = 10 mph

Let the speed of the current = x

Upstream speed = 10 - x

Downstream speed = 10+x

Upstream Distance = 4 miles

Downstream Distance =  6 miles

Time taken on upstream =  

Time taken on downstream =  

Same time taken for both upstream and downstream

So

Cross multiply it

4(10+x) = 6(10-x)

40 + 4x = 60 -6x

Add 6x  and subtract 40 on both sides

10x = 20 (divide by 10)

x= 2

So speed of the current = 2.0 mph

huh? im pretty sure it is in 199
