= 5 hour
Answer: No. 2
A cyclist covers a distance of 15 miles in 2 hours
[tex]speed = \frac{distance}{time} = \frac{15}{2} [/tex]
= 7.5 miles per hour. is the answer
Answer: No. 3
[tex]speed = \frac{40 \: miles}{hr} [/tex]
[tex]distance = v \times t = 4 \times 40 \: = 160 \: miles[/tex]
now the speed will be it's cover this distance in 1.5 hours
[tex]v = \frac{d}{t} = \frac{160}{1.5} = 106.67miles(hr[/tex]
So the speed is 106.67miles/hr
Answer: No. 4
