You can put this solution on YOUR website!
Lety +t+ = her time in minutes
for her 8th ride
-------------------
+%28+46+%2B+48+%2B+50+%2B+43+%2B+54+%2B+54+%2B+52+%2B+t+%29+%2F+8+=+51+
+347+%2B+t+%29+%2F+8+=+51+
+347+%2B+t+=+408+
+t+=+61+
She needs a time of 61 min on her 8th ride
in order to average 51 min for the 8 rides
