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

b

Explanation:

yes

Answer 2

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

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 =
`(Distance)/(Time)`

Let take this as S1 =
`(D1)/(T1)`

S1 =
`(0.5)/(6)` mile per min

S1 =
`(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 =
`(SD2)/(T2)`

S2 =
`(6)/(0.5)`

S2 = 12 mile per hour

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