You can put this solution on YOUR website!
d = distance from Glen Rock to Oakville in km
t = time prop plane takes in hours
t-4 = time jet plane takes in hours
d+%2F+t+=+273
d+%2F+%28t-4%29+=+637
d+=+273t
d+=+637t+-+2548
273t+=+637t+-+2548
364t+=+2548
t+=+7
d+=+273t
d+=+273%2A7
d+=+1911 km between the towns
check
d+%2F+%28t-4%29+=+637
1911+%2F+3+=+637
637+=+637
OK
