64 percent Tom is riding his bicycle. He rides at a speed of 11 kilometers per hour for 17.6 kilometers. For how many hours does he ride?
Hi! Let's start with an easier problem: if he rides at 11 kilometers per hour for 11 kilometers, for how many kilometers does he ride?
Ooops, I meant "for how many hours does he ride?" Sorry!!

Great! Now suppose it was for 22 kilometers?

Exactly! How about 55 kilometers?

That's right! Now lets go back to your question: what about 17.6 kilometers?
(This is a bit harder than 55 km, but it's the same idea. Do you need a hint?)
1.6?
Perfect! Well done! :)
64 percent from the first line what mean ?
thanks
one mor easy way to solve it using the rule of 3 simple so write 11 km -------------- 1 hour 17,6 km ------------- x ------------------------------- x = 17,6 *1 / 11 = 17,6/11 = 1,6 hour x=1,6 hour hope this is understandably too
