It is a case of direct variation...
3/x = 4/48
4x = 48 × 3
x = 48 × 3/ 4
x = 36 metres
4/48 = d/84
48d = 4 × 84
d = 4 × 84/ 48
d = 7 min
7/84 = 25/@
7@ = 25 × 84
@ = 25 × 84/7
@ = 300 metres
25/300 = &/1860
25 × 1860 = 300&
25 × 1860/ 300 = &
& = 155 min
3/x = 4/48
4x = 48 × 3
x = 48 × 3/ 4
x = 36 metres
4/48 = d/84
48d = 4 × 84
d = 4 × 84/ 48
d = 7 min
7/84 = 25/@
7@ = 25 × 84
@ = 25 × 84/7
@ = 300 metres
25/300 = &/1860
25 × 1860 = 300&
25 × 1860/ 300 = &
& = 155 min
