If it took Oscar T hours to travel 88 miles, Pablo took T%2B3 hours. If Pablo can ride his bike at a speed of V, Oscar can ride at a speed of 4V.
Lets write down equations using the above data.
+88+=+V%2A%28T%2B3%29 (Distance=Speed*Time)
88+=+4V%2AT
multiply first equation by 4...
352+=+4VT+%2B+12V
subtract the second equation from this,
264+=+12V
V+=+264%2F12+=+22+ miles per hour (The speed of Pablo)
