Question

marcus wants to find the speed of a train that traveled 1/2 of a mile in 6 min. sanjay wants to find the speed of a train that traveled 6 miles in a 1/2 of an hour. whose problem is best modeled by a division expression ​

Answer 1

Answer:

Sanjay calculation of Train speed is more than Marcus calculation of Train speed

Step-by-step explanation:

Given in question as

Marcus want to calculate Train speed , covering distance of 0.5 mile in 6 min

Now as we know that Speed = $\frac{Distance}{Time}$

Let take this as S1 = $\frac{D1}{T1}$

                           S1 = $\frac{0.5}{6}$ mile per min

                           S1 = $\frac{60}{12}$ mile per hour    

                            Note 1 hour = 60 min

                           So, S1 = 5 mile per hour  

Now ,  Sanjay want to calculate the Train speed , covering distance of 6 mile in 0.5 hour

Let take   S2 = $\frac{SD2}{T2}$

                S2 = $\frac{6}{0.5}$

                S2 = 12 mile per hour

Hence We can say that Sanjay calculate  more Train speed than Marcus .
