Given that Distance = 2 5/8 miles = 21/8 miles

Time = 3 and 1/2 minutes = 7/2 minutes

Then speed of the car is given by formula :[tex] Speed=\frac{Distance}{time}=\frac{\frac{21}{8}}{\frac{7}{2}}=\frac{21}{8}*\frac{2}{7}=\frac{42}{56}=\frac{3}{4} [/tex]

miles per minute

Hence distance travelled in M minutes will be given by equation

[tex] D=\frac{3}{4}M [/tex]
