Question

Go. A cyclist moves at uniform speed. If he can cover 85 km 705 m in
5 hours, what distance will be covered in 8 hours ?​

Answer 1

Answer:

137km and 128m in 8 hours

Step-by-step explanation:

First, let's make 85km and 705m into pure meters. Since there are 1000 meters in a kilometer, you multiply 85km by 1000m/km

85km x 1000m/km

The km cancel out:

85 x 1000m = 85,000m

So now you add:

85,000m + 705m = 85,705m

So our rate is 85,705m per 5 hours

We can turn this into a ratio:

85,705:5

We want to find out how many meters he goes in 1 hour, so we divide both sides of the ratio by 5.

85,705/5 = 17,141

5/5 = 1

So our new ratio is:

17,141:1

OR

17,141m per hour

Now we multiply both sides of the ratio by 8 to find out how far he went in 8 hours.

17,141 x 8 = 137,128

1 x 8 = 8

So our ratio is:

137,128:8

OR

137,128m per 8 hours

Now we can convert this back into km, we do that by dividing the number by 1000.

137,128/1000 = 137.128km per 8 hours

OR

137km and 128m per 8 hours

SO

The cyclist will cover 137km and 128m in 8 hours
