Swimming
Distance: \(S\) miles
Time: \(H\) hours
Riding
Distance: \(B\) miles
Time: \(4H\) hours
Average speed = \(\frac{Total-distance}{total-time}\)
= \(\frac{S + B }{ 5H}\)
Answer A
Distance: \(S\) miles
Time: \(H\) hours
Riding
Distance: \(B\) miles
Time: \(4H\) hours
Average speed = \(\frac{Total-distance}{total-time}\)
= \(\frac{S + B }{ 5H}\)
Answer A
