Question

randon enters bike races. He bikes 91 half miles every1 half hour. Complete the table to find how far Brandon bikes for each time interval. (ignore the numbers in the boxes i put them and they were incorrect)

Answer 1

It is given that in every 1/2 hours Brandon bikes .

The distance 8 1/2 miles is in the form of mixed fraction.

Therefore, the distance 8 1/2 miles can be written in the form of decimal as follows:

8 1/2 miles = 8.5 miles

Brandon bike's 8.5 miles in every 1/2 hours .

We know that 1 hour is equivalent to 60 minutes .

So, 0.5 hours can be converted into minutes as follows:

1 hour = 60 minutes

1.5 hours= 30 minutes

Therefore, in every 30 minutes Brandon bikes .

So, in next 30 minutes Brandon also bikes 8.5 miles .

In every 1 hour Brandon travels = 8.5+8.5 = 17 miles.

In every 1:30 Brandon travels 17 +8.5 =25.5 miles.

Method 2:

Speed of Brandon’s bike can be calculated as ,

speed = distance/time

Here, d is the distance and t is the time.

Now, substitute d=8.5 and t= 0.5 in the equation (1)

Therefore, the rate of travelling of Brandon’s bike is .

The distance of Brandon’s bike in each interval of time can be represented in the attached Table 1.

Hope this helps you!!!!!!!!!!!!!!!!!!!!!
