Question

Jamil traveled 210 miles, which is 70% of the total distance to his grandfather's house. How many more miles does he need to travel to reach his grandfather's house?

Answer 1

Hello Dalinda,

Here is the solution to the problem:

 

Let us suppose the total distance = x miles.

Distance already traveled = 210 miles

 

According to the question,

Distance already traveled = 70% * total distance

210 = 70% * x

210 = 70x/100

210 * 100 = 70x

(210 * 100)/70 = x

x = 300

 

Thus total distance = 300 miles

Distance remaining to travel = 300 - 210 = 90 miles.

 

Answer = 90 miles.

 

 

Hope it solves your doubts.

Answer 2

210 is 70% of what number ?

210=70%*n

210=0.7*n

2100=7n

n=2100/7

n=300 miles

300-210=90 miles more
